From the mail bag…
I purchased this audio decoder http://ift.tt/1CKak1Y, a 3.5mm headphone jack, and one of your Perma-Proto half-sized breadboards. I wanted to make a simple radio prop that played static all the time, but interrupt it and play certain radio broadcasts when triggered. This was my first real electronics project, so I was worried I would short it out or touch two wires the wrong way and connect something wrong and ruin the board.
But after a lot of trial and error, it turned out great and works perfectly. I plugged in the speakers and heard static, and when I flipped the switch and heard the radio broadcast I cannot tell how excited I was that it worked, and felt compelled to write this. Thank you so much for making my first project a memorable experience.
